ZEBROS PROJECTS DEVELOPMENT OF HALL SENSOR PROPELLER ANEMOMETER FOR MEASURING WIND SPEED USING EMBEDDED CONTROLLER ABSTRACT An Anemometer is a device for measuring wind speed. Propeller type anemometer measures wind speed by generating an A.c signal. In the development of new anemometer, we use Hall Effect sensor to generate digital signal. The voltage levels of the digital signal depends on the input voltage applied to the Hall sensor, its input voltage may be from 2.5V - 27V. The Timer/Counter is a register in the Microcontroller, whose value keeps increasing or decreasing for rising edge or falling edge of the internal or external clock source by a constant rate without the help of CPU. The external clock to the counter is the digital signal from the Hall sensor. Thus the rate of rotations made by the propeller is counted using counter in the PIC 18F series Microcontroller. The spinning rate of the propeller is proportional to the wind speed. Therefore, we can determine the wind speed from the measurement of spinning rate of the propeller using embedded controller and the radius of propeller. The performance of our system is compared with existing system and our designed anemometer is also inexpensive. EXISTING SYSTEM An induction or asynchronous motor is an inherently self-starting AC motor in which energy is transferred by electromagnetic induction from a primary winding to a secondary winding. The two windings being separated by an air gap and such transfer usually from the stator to either a wound rotor or a short-circuited squirrel cage rotor. It is the existing system. Induction motor is used here. Induction motor used is three phase induction motor. It is advanced than single phase induction motor. Three phase induction motor is self-starting. It is an asynchronous motor. Speed can be controlled by varying the voltage.

ZEBROS PROJECTS This existing system is high cost, rugged performance, could not accurate measuring. PROPOSED SYSTEM Wind speed can be measured at an accurate for the light below of winds. As the system counts the rotations made by the propeller, then Hall Effect sensor generate a digital signal. Digital signal system works on digital signal, so it is easy to measure through microcontroller. In the a.c signal generator type anemometer, the a.c sine wave signal is induced by rotating magnet on propeller shaft that produces 80 m Vpp at 100 rpm and 8Vpp at 10,000 rpm.But in our developed anemometer, the digital signal has a constant peak to peak voltage depends on input voltage applied to Hall Effect sensor and the waveform generated. Each digital pulse represents one complete rotation made by the propeller. Even at low wind speed propeller makes slow spins that also detects and converted into wind speed. In a.c signal type anemometer data acquisition system is required to convert a.c to d.c signal, but in our measurement system needs no conversion from a.c to d.c signal.
BLOCK DIAGRAM CONTACT: ZEBROS PROJECTS PHONE: 9940098300, 9500075001 DESCRIPTIONS This system aims at monitoring the speed and control in wind motors. An embedded system is used for acquiring electrical signals from the motors in a noninvasive manner. It performs local processing for speed and torque estimation. The values calculated by the embedded system are transmitted to a monitoring unit through a ZigBee based wireless sensor network. Local processing capability is essential for this type of application.

ZEBROS PROJECTS A fix magnet is attached onto the aero vane propeller. When the wind blows, the propeller will spin relative with the wind speed, thus the magnet will trigger the Hall Effect sensor. A pulse will be generated as an output for each revolution. The time difference from each pulse is used to calculate the speed of the wind. At the same time, the tail of the aero vane will direct according to wind direction. The Aero vane is attached with potentiometer which will give analog signal output with respect to the direction of the wind. The analog signal is being converted into 8-bit binary by the analog to digital converter module in microcontroller. A fix magnet attached on propeller will trigger the Hall Effect sensor thus giving a pulse for each revolution Processing signal on microcontroller Display measured wind speed and wind direction. Direction of wind was reflected by aero vane model and then is being coded into binary code representing specific direction. The output from Hall Effect sensor and potentiometer will be transmitted to microcontroller to be processed and calculated. The calculated measurement will be displayed on the LCD. The LCD used is the 16 characters and 2 lines type. It will be displaying the speed of the wind in km/h unit with the direction of the wind in a specific direction. ADVANTAGES

What is IEEE? The Institute of Electrical and Electronics Engineers or IEEE (read eye-triple-e) is Incorporated in the State of New York, United States. It was formed in 1963 by the merger of the Institute of Radio Engineers (IRE, founded 1912) and the American Institute of Electrical Engineers (AIEE, founded 1884). A membership organization comprised of engineers, scientists and students that sets standards for computers and communications. It is a nonprofit organization with more than 365,000 members in around 150 countries. The IEEE describes itself as "the world's largest technical professional society -promoting the development and application of electro technology and allied sciences for the benefit of humanity, the advancement of the profession, and the well-being of our members." Why IEEE based projects?
It grantees for standard It assured latest solution for problems It delivers new patented technologies at an ever-increasing pace
